This shirt fits beautifully and provides great visibility. I most recently used it during a half marathon where the weather a balmy 46 degrees, spitting rain, and pretty windy. The description of the shirt states that it's good for 40-60 degrees and I found that it was a bit thin for the colder temps, but it fit GREAT. I'm a scrawny 5'4" and the shirt fits very nice. I usually have problems finding shirts that are too long and/or too wide. This shirt is a tad bit longer than I'd like, and the width is perfect! Overall, I'm extremely happy with my purchase.

I used this product for a long run beginning at 5:30 a.m. when the temperature was low at or about 45 degrees.

The material kept me comfortable enough throughout the run, including when the temperature warmed-up later in the morning to about 70 degrees. Wearing another layer, either beneath or over, was not necessary. The soft, moisture-transfer mesh is also lightwieght and moisture wicking which kept me dry and prevented any skin irritation or chafing.

One suggested improvement to this product, or something similar to it in the future, is that the tags placed at the inside of the shirt, hip-level, be made with softer material, as I felt the tags attached there while running. One may wish to remove the tags completely to avoid unecessary distraction or discomfort. Another critique is that it lacks ports for headphone cable management. I may not always run with headphones, but if I chose to while wearing this product, the cables would hang from my ears, toward my back and connect to my music player on my upper arm. A design to help swinging headphone cables (like other running shirts I own) would be another suggested improvement here.

Overall, this is a great product and I run happy that I purchased one.

Nothing wrong with the shirt. I love the look of this and it's sleeveless version, bought one of each. My only gripe is that they seem to fit a little larger than other "large" running shirts I have ... Next time will try a Medium

I run about 23-28 miles a week, and this is my first winter running outdoors. I've used this shirt a few times as an outer layer for days that are 30-45. For me, it's a great fit to go over a fitted under-layer, but I'm right at the large/medium chest size, so keep that in mind when you're evaluating. It's also a good weight for keeping the warmth in, but keeping the total outfit weight down. Over all a good piece of clothing.

This shirt looks and feels great. It it lighter than other long sleeve ts I own but no cooler. My only beef is that it is a little small in the shoulders (if you're particularly broad-shouldered beware) and simultaneously long in the sleeve. I feel as though I can't go up in size because of the sleeves so I'm living with the shoulders. I haven't checked the reflectivity of it, yet.
